Hydrodynamics in a Bubble Column—Part 2: Three‐Phase Flow
Multiphase computational fluid dynamics (CFD) simulation is a useful tool to study the hydrodynamics in a bubble column, if appropriate closure models exist. The present study extends a previous database to three‐phase flow experiments. This is achieved by using a combination of particle image velocimetry (PIV) and shadowgraphy to measure all phases ...

Characterization of extrusion flow using particle image velocimetry
The aim of this study was the characterization of polymer flows within an extrusion die using particle image velocimetry (PIV) in very constraining conditions (high temperature, pressure and velocity).

The development of microelectromechanical systems based on magnetohydrodynamic for micro-robot applications requires precise control of the micro-flow behavior. The micro-flow channel design and its performance under the influence of the Lorentz force is

Laser bathymetry on rough riverbed channels: State‐of‐the‐art and future prospects
This literature review found that topo‐bathymetric LiDAR has been successfully used to capture the structures of rough riverbeds and detect large boulders. While all of the studies that were reviewed used sensors that were operated from fixed‐wing aircraft, few studies have yet tested UAV‐borne sensors on rough riverbeds, despite the potential offered ...

Analysis of turbulence and vortex structures by flow mapping
The technique of Particle Image Velocimetry (PIV) flow mapping is reviewed and comparisons made with Laser Doppler Anemometry (LDA). Results are presented showing the application of PlV to the determination of coherent structures in grid-generated ...

Frequency-division-multiplexing technique for imaging metrology [PDF]
An algorithm to multiplex multiple image captures simultaneously onto a single image sensor at full frame resolution was developed for imaging metrology. Parseval’s theorem was used to obtain the image intensity from image time-series of around typically

Hydrodynamic and ecological effects of engineered logjams: Insights from field observations
Drone imaging, LSPIV and electrofishing data quantified restoration effects of engineered logjam at the Emme River (Switzerland). Placement and discharge shaped flow: Side jams created longer wakes, centre jams stronger mixing; and lower discharge intensified gap velocities, whereas wake length remained stable.

The investigation of tube sampling disturbance using transparent soil and particle image velocimetry [PDF]
A small-scale physical modelling system was developed and employed to investigate the effects of tube sampling. Amorphous silica and an oil blend of matching refractive index were mixed to form a transparent soil.
